I actually didn't get a price yet, they are calling me back on the 7". Online its about $17 for a 5 foot 6" and $21 for a 5 foot 8". Wasn't planning on spending more than ~$4-5 per linear foot.
Dust Collector is 3HP Oneida V-3000.
My pricing estimate for 26ga snaplock is ~$800, spiral at ~$900. $250-$300 for shipping on either one.
Oneida is coming out about the same as theblastgateco.com - their shipping costs are basically built in to their pricing, they are within $40 all-in.
Also the shop inside wall dimensions are ~18.5x26.5
